RArLWAY RAIL.

Application filed November 11, 1927. Serial No. 232,536.

As is well known, erails wear where the treads of wheels pass over them and also where the 'flanges of wheels engage them and that rails are worn out when good in all other parts.

The object of my inventionv is to provide a rigid rail with an easily replaced tread and this rail is simple in construction, durable in operation and easyto manufacture. This and other objects are accomplished by myl invention, one -embodiment of which is hereinafter more particularly set forth.

Fora more d-etailed description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which:

Figure l shows a track provided with my improved rail.

Figur-e 2 shows a cross vsection of my improved rail.

Figure 3 a plan view with parts broken away to more clearly reveal the structure.

Throughout the various views of the draw ings, similar reference characters designate similar parts.

My improved rail l. is placed on cross ties 2, in the conventional manner. This rail has a tread 8, clamping plates 4 and a base 5 which has upright flanges 6 and laterally extending webs 7 which are adapted to rest on cross ties 2, in the conventional manner. The clamps el. and base 5 are held by suitable clamping bolts 8 which are provided with suitable washers 9 so that the` parts may be firmly clamped together.

The tread l) of the rail is given any desired shape on its top and on its lower surface is inclined inwardly and downwardly to a center projection 10 which is enlarged to enter corresponding grooves in the clamps Ll and to prevent creeping, from time to time at desired intervals, the projecting` part l0 is provided with laterally extending lugs ll`r which are 'properly spaced and adapted to engage corresponding recesses l2 in the clamp plates il; so as to prevent creeping.

rl"he clamps Ll are preferably made to rest against each other, as shown at 13 in Figure 2, and they rest firmly on top ofV the vertical flanges 6, as shown in this figure. These clamps are provided with laterally extending webs 14 to give the requisite stiff'- ness to the structure.

The base 5 is made in one integral mass and rigid so that the rail may have the reqf uisite rigidity when in use. It will be noted that the flanges 6 are paralleland spaced well apart from the vertical neutral anis of the rail so as to provide a very stiff' rail which will resist all side thrustsdue to the conditions ol service and thewebs 7 and l-l on the base and clamps il, respectively, are placed away troni the neutral axis so as to resist all bending of the rail when carrying a load.

Because of the disposition of metal, as herein set forth, my improved rail has more than ordinary rigidity so that the metal therein is more eflicient than the metal in ordinary rails.

Then laying the rail, care should be taken to see that the joints are broken as much as possible tween the treads 3, the clamps l and the bases 5. This tends to give a smoothness of operation to all trains passing over the rail ybecause of the eXtreme rigidity of the structure above set forth.

In view of the foregoing, the operation of my improved rail will be readily understood. It is installed. and used much as ordinary rails are installed and used with this exception. The assembly'occnrs on the job, they bases 5 being rst secured in place and the tread 3 and clamps 4 are thereafter put in position and finally held by the bolts 8, as above set forth. Then any tread or treads 3 become worn out or undesirable for any reason, it or they may be readily removed and new ones substituted, as is obvious without disturbing any great length of rail and the clamps l and bases 5 as well as the bolts S are permanent and may be used indefinitely'.

lVhile I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but that it broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described my invent-ion, what I claim is: i

l. A rail with an integral beschaving upwardly extending. parallel fiangesclamps mounted on said flanges and a tread engaging said clamps, the tread, clamps and base being `held in fixed relation by suit-able securing` means..

2. A railway rail composed of an integral base having upwardly extending lianges.I clamps with parts resting on said base and provided with laterally extending'flanges. a tread with means to prevent creeping held by said clamps and means for' rigidly conmeeting the hase, the clumps und the tread.

3. A rail composed of an integral base with upwardly extending flanges, clamping members resting on and against said ianges and provided with laterally extending Webs at their lower edges and tread receiving parts at their upper edges, a tread clamped by said clumps and means for holding the same in rigid relation therewith and means for rseeuring the tread, clamps and hase 10 iXedly together.

In testimony whereof, I have hereunto set my hand this 5th day of November, 1927.
